General note An oil cooler is available for this engine from BRP-Powertrain (see Illus-
trated Parts Catalog).
NOTE: Experience has shown that an oil cooler of at least
160 cm
2
(25 in
2
) is required, provided that air flow is ade-
quate.
3.1) Permissible position and location of the oil cooler
Installation See Fig. 11.
- The oil cooler should always be installed below the engine oil pump.
Non-compliance can result in serious injuries or
death!
Certification according to the latest regulations, such
as FAR or EASA, must be conducted by the aircraft or
fuselage manufacturer.
The oil cooler must be designed to dissipate approx.
10 kW (7.58 BTU/s) of thermal energy at take-off per-
formance.
The oil cooler must not restrict oil flow. Test system as
per chap. 79-00-00 section 1.3.
Non-compliance can result in serious injuries or
death!
The oil cooler must be designed and installed such
that the permissible operating temperatures are main-
tained and that these do no exceed or fall below the
maximum values.
This must also apply to "hot day conditions".
If need be, take appropriate measures such as chang-
ing the size of the oil cooler, partially covering the
cooler, etc.
The oil cooler must be installed with the radiator caps
pointing upwards i.e. in positive direction on the
z-axis.
